Problem with feed not syncing again.

[Backwoods Bedroom]

Hello,

Please help.My feed is not updating again. I had wrongly assumed that I had fixed the issue, but apparently not. Steps I've taken to resolve this time.

1 .I disabled feeds from being cached on WP Super Cache. 

2. I've went to through all the troubleshooting. 

3. When I ping Feedburner using my url: http://backwoodsbedroom.com I get an error message which I attached a screenshot of. 

4. The feed validates with some recommendations. http://backwoodsbedroom.com/feed/

5. The feed address fails to vailidate though.(Attached screen shots)  http://feeds.feedburner.com/BackwoodsBedroom

6. I further went on to Resync and it still did not fix the issue. 

You can see on this board this happened before. I thought the issue was with Super Cache, but apparently that is not the issue. 

Hope you can help me understand the issue and resolve it once and for all. I appreciate your help very much. Thank you in advance.

I seemed to have fixed the issue again. I deleted the cache, I also lowered Syndication feeds show the most recent from 10 to 8. 

What do you think resolved the issue?
